BICYCLE-GUARD.

SPECIFICATION forming part of Letters Patent No. 592,987, dated November2, 1897.

Application filed April 1, 1897. Serial No. 630,314. (No model.)

To 62% whom it may concern:

Be it known that I, Anznr N. HEMINGER, a citizen of the United States,residing at Plymouth, in the county of Marshall and State of Indiana,have invented certain new and useful Improvements in Bicycle-Guards; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has relation to bicycles; and it consists in certaindetails of. construction and arrangement of parts necessary to provide ahousing or protection for the sprocketwheels and sprocket-chain thereforand incidentally a protection for the bearings.

The object of my invention is to protect the parts specified frombecoming soiled or injured by mud, dust, or the like, and also toprovide means for protecting the garments of the rider againstmutilation or from becoming soiled.

The details involved will be clearly set forth in the accompanyingdrawings, made a part of this application, in which- Figure 1 is a sideelevation showing my invention applied to use upon the frame of abicycle. Fig. 2 is an elevation of the opposite side of the protectorillustrated in Fig. 1. Fig. 3 is a longitudinal vertical section of thehousing or protector. Fig. 4 is a detail showing a modified constructionfor securing the overlapping ends of the sections forming the housing.Fig. 5 is a vertical transverse section of Fig. 2 on line a a.

Reference to the various details involved will be had by figures, thesame figure being employed to designate the same part throughout theviews.

Briefly stated, my invention may be said to consist in providing ahousing formed of two sections, one to receive or inolose the upper halfof the sprockets and chain, while the lower section will. receive andprotect the lower half of said parts, and also in the provision of meansto effect the locking of the two halves of the housing together in an adjusted position.

In materializing my invention I provide the members 1 and 2, forming,respectively, the upper and lower parts of the housing.

Said section 1 is of sufficient length to extend from one sprocket-wheelto the other and consists of the parallel side walls 3 and 4 and theroof-section 5, said section being extended at either end to form theend walls 6 and 7, while the lower part of the housing consists of theparallel side walls 7 and 8 and the floorsection 9, coinciding inposition and extent with the upper part of the housing just referred to,the floor-section 9 being extended in a similar manner at either end toprovide the end sections 10 and 11, said sections being designed tooverlap the end sections 6 and 7 of the upper part of the housing. Inorder that said overlapping sections may be easily locked in an adjustedposition, I provide that each shall have a series of corrugations 12,which will take into or interlock with each other, when the parts willbe reliably held in position by the tensile property of the spring-likematerial forming said ends.

If deemed desirable, the interlocking of the ends may be reinforced byproviding that one of the overlapping ends shall be provided with a11001: 13, designed to take into one of the series of apertures 14,provided in the contiguous part of the end wall of the upper section.

In Fig. 4 I have shown a locking device of more positive character, aclip 15 being socured, preferably, to the lower part of the easing andthe overlapping end wall of the other section being formed with athreaded terminal or bolt 16, which will take through said clip and beheld therein bya suitable nut.

In mounting the parts of the housing in their operative positions itwill be observed that the horizontal section 17 of the frame will takeobliquely through the housing, and in order to enable the parts to besnugly fitted together, so as to accommodate said section of the frame,I prefer to provide the angular reoess 18 preferably in the lower halfof the housing, said recess being formed in the walls 7 and 8 uponeither side, each recess extending sufficiently near to receive thecontiguous section of the part 17 of the frame.

In order to reliably anchor the housing in position, I provide theclamps 19 and 20, the former being permanently secured to the upper partof the housing upon the outer side thereof by means of the rivet 21 orotherwise.

It will be observed that said clamp is of sufficient length at one endto encircle the rear part 22 of the frame, while the lower end thereofextends into engagement with the lower part of the housing, to which itis adj ustably secured by means of the slot 23 and the set-screw 24.

The clamp 20 is adjustably affixed to the upper part of the housing bymeans of the slot 25 and the set-screw 26, while the free end 27 isdesigned to take around and engage with the contiguous part of theframe, the slot 25 permitting the proper adjustment of the clamptoenable it to be readily adjusted upon any machine.

If deemed desirable, the upper and lower sections of the housing may bemore securely held together by providing the adjustable clamps 28, 29,and 30, as clearly shown in Figs. 1 and 2.

It is thought that by providing that the end walls have sufficientresiliency-no other means than the corrugations will be found necessaryto hold the upper and lower parts in an adj usted position, as the endwalls will cling into engagement with each other by means of theconstruction described.

The use of myinvention may be stated to be as follows: The parts formingtheupper and lower sections of the housing are placed upon the preferredmachine in such a manner that the overlapping corrugated end walls willengage with each other, when by forcing the parts together thecorrugations upon said Walls will move past each other until the partsof the housing are brought sufficiently near, when the clamping strainof said walls, due to the resiliency of the metal forming the same, willreliably hold them to their work, when the free end of the outer wallhaving the hook 13 will be in such a position that said hook will takeinto one of the apertures provided therefor.

In order that the garments of the rider may be additionally protectedand held entirely away from contactwith the rear wheel, I provide theshield 31, secured, preferably, to the inner part of the upper half ofthe housing by means of the set screws or rivets 32, or otherwise. Saidshield is provided witha series of perforations 33, designed to receivethe interlacing of a tape or cord which cooperates with the upperportion of the frame in such a manner that a reliable guard is woven orformed by passing upward and downward, the lower ends of the loops beingformed by said perforations 33.

In order that the sprocket-chain may be readily oiled Without thenecessity of removing the housing, I provide the oil-receiving apertures34, formed in the roof of the housing, as clearly set forth in Fig. 3.

In order that any surplus oil falling from the sprocket-chain maybeconveyed through the floor of the housing and thence to the ground, Iprovide the orifices 35, thus preventing the oil from draining to theforward or rear ends of the housing and there come in contact with thegarments of the rider.

It will be observed that I have produced a simple, cheap, and reliablyefficient means for protecting the bearings and sprocket- Wheels andgarments of the rider and that the parts forming the protector orhousing may be readily assembled and applied to use upon any machine,and believing that the advantages, use,and constructionthereof have beenmade fullyapparent further description is deemed unnecessary.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The herein-described attachment for bicycles consisting of the upperand lower members designed to provide a housing for the sprockets andchain therefor, the end walls of each member being extended and providedwith corrugations for engagement with each other and means,substantially as described, for locking said sections in an adjustedposition, as set forth.

2. The herein-described adjustable guard for bicycles consisting of theupper and lower members designed to provide a housing for thesprocket-wheels and chain therefor, each member being provided withcurved end extensions having corrugations and designed to overlap andengage each other; a hook formed upon'the end of one of said corrugatedextensions and apertures designed to receive said hook formed in acontiguous part of the opposite extension; a perforated plate secured tothe upper member, and

- means substantially as described, for anchoring said members in theiroperative position upon the bicycle-frame,substantial] y as specifiedand for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
